ABSTRACT:
A process for hydrogenating coal which has been mixed with oils, by bringing the coal slurry to the reaction pressure by pumping, heating the slurry and catalytically hydrogenating it with hydrogen, wherein some or all of the hot gases and vapors formed during hydrogenation are intimately re-mixed with the coal slurry in a plurality of stages. After the first mixing stage, the gases are freed from the product, and the product-free gases, especially hydrogen, are used as a thermal medium.
